PURPOSE:To provide the titled compsn. yielding plating films excellent in heat cycling resistance and peeling strength, by incorporating three particular copolymers with a fluorine surfactant. CONSTITUTION:15-75pts.wt. polybutadiene latex, 5-95pts.wt. graft copolymer in which an arom, monovinyl monomer (a) and a vinyl cyanide monomer (b) are partially grafted onto said polybutadiene latex, 100pts.wt. mixture of 95-5pts.wt. graft copolymer in which the component (a) and the component (b) are partially grafted onto 15-75pts.wt. styrene/butadiene copolymer having the content of styrene of 5-45pts.wt. with 0-85pts.wt. copolymer of 50-85pts. wt. component (a) and 50-15pts.wt. component (b), and 0.01-3.0pts.wt. fluorine surfactant (e.g., perfluoroalkylcarboxylic acid salt) are incorporated. |
